What a horrible situation for you to be in.

I'm sure you would have done counselling before you started IVF, so maybe your DH has just started to freak out. But if he continues to proceed with divorce then it is his loss, yes having twins is hard work but they are will also provide you with such joy as well.

I would also recommend you make contact with your local Multiple Birth Association in your area, each one offers different services and you might find some extra support. Plus they may also be able to help you with being able to get items for your babies as parents of older twins always have lots of stuff to get rid of. Once your twins are born you may also be able to get support services through your local council to help you get over the initial period of getting them home and into a routine, the support services can offer things like general housework or even respite care to look after the babies so you can get out and do shopping ect.

Also once they arrive if you struggle to breastfeed then one of the formula companies offers a substantial discount on formula as well (almost 50% off) so there are a lot of options available to you.

I hope things start to look more positive for you soon.
